On October 29th, 2025, the interstellar object 3I/ATLAS the third visitor ever detected from beyond our solar system reached perihelion, its closest point to the Sun.
What astronomers expected to be a routine solar encounter turned into something no one could explain.
In a matter of seconds, 3I/ATLAS flared more than four magnitudes brighter, splitting into multiple fragments and releasing an energy burst seen simultaneously across the planet.
From Australia to Chile, telescopes everywhere recorded the same event at the exact same moment a global first in the history of astronomy.
The flare defied every known model of comet physics.
Spectroscopic data revealed a metallic composition dominated by nickel and iron, with no sign of the water ice or carbon gases that define normal comets.
There was no visible tail, no solar outburst to trigger it just a sudden, symmetrical explosion of light.
Now, scientists are re-examining everything we thought we knew about interstellar objects.
Was this a natural phenomenon, or did we just witness something beyond our understanding?
Join us as we break down the data, the evidence, and the mystery of 3I/ATLAS at perihelion the day every telescope on Earth saw the impossible.
